Don't stop believing– you can get tickets anytime you want in San Francisco!
As of the time of this post (it is 3:28 EST,12:38 PST), tickets are still available for Game 3 of the NLCS, which starts in exactly 51 minutes.
That's right folks, you can get a single seat in the first level or a pair in the upper-deck right from SanFranciscoGiants.com!
These aren't ones that were set aside either, they are still advertising packages on the site.
Nice fan base, San Francisco Giants.
H/T to Ashley for the heads up
